We also have uncommitted lines of credit with various banks which permit borrowings at variable interest rates and which are primarily used to fund working capital needs. We have guaranteed the repayment of some of these borrowings made by certain subsidiaries. If we lose access to these credit lines, we would have to provide funding directly to some of our international operations. As of June 30, 2017, the Company had uncommitted lines of credit in an aggregate amount of $906.5, under which we had outstanding borrowings of $237.7 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the second quarter of 2017 was $457.6, with a weighted-average interest rate of approximately 2.2%.
In June 2017, the Company established a commercial paper program under which the Company may issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,000.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper will be used for working capital and general corporate purposes, including the repayment of maturing indebtedness, as described above, and other short-term liquidity needs. The maturities of the commercial paper vary but may not exceed 397 days from the date of issue. As of June 30, 2017, there was no commercial paper outstanding. From the date the program was first utilized through June 30, 2017, the average amount outstanding under the program was $203.7, with a weighted-average interest rate of 1.4% and a weighted-average maturity of seven days.
We aggregate our domestic cash position on a daily basis. Outside the United States, we use cash pooling arrangements with banks to help manage our liquidity requirements. In these pooling arrangements, several IPG agencies agree with a single bank that the cash balances of any of the agencies with the bank will be subject to a full right of set-off against amounts that other agencies owe the bank, and the bank provides for overdrafts as long as the net balance for all the agencies does not exceed an agreed-upon level. Typically, each agency pays interest on outstanding overdrafts and receives interest on cash balances. Our unaudited Consolidated Balance Sheets reflect cash, net of bank overdrafts, under all of our pooling arrangements, and as of June 30, 2017, the amount netted was $1,512.9.
DEBT CREDIT RATINGS
Our debt credit ratings as of July 17, 2017 are listed below.
Moody’s Investors Service
S&P Global Ratings
We are rated investment-grade by Moody's Investors Service, S&P Global Ratings and Fitch Ratings. On June 8, 2017, we received from the credit rating agencies the short-term credit ratings, described above, with respect to our commercial paper. The most recent update to our long-term credit ratings occurred in April 2017 when S&P Global Ratings upgraded our rating from BBB- to BBB with a Stable outlook. A credit rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning credit rating agency. The rating of each credit rating agency should be evaluated independently of any other rating. Credit ratings could have an impact on liquidity, either adverse or favorable, because, among other things, they could affect funding costs in, or the ability to access, the capital markets or otherwise. For example, our Credit Agreement fees and borrowing rates are based on a long-term credit ratings grid.
